40 Claims.

This invention relates to machines for use in the manufacture of shoesand is herein illustrated as embodied in a machine for use in assemblingthe upper of a tennis shoe or sneaker on its last and for securing theupper to an insole on the last preparatory to the lasting of the upperby means of a machine such, for example, as that disclosed in UnitedStates Letters Patent No. 1,843,232, granted February 2, 1932, uponapplication of the present inventor.

In the manufacture of tennis shoes it has been the practice for thelasting machine operator, after having mounted a last, having an upperloosely assembled thereon, upon the spindle of the lasting machine andbefore starting the machine, to pull the upper forwardly by his fingersso as to draw it closely about the heel portion of the last, and also topull the opposite side portions of the upper upwardly by his fingers, todraw the upper closely about the forepart of the last, and finally toplace an insole in proper position upon the last bottom.

One object of the present invention is to provide a machine which iswell adapted for performing such preparatory operations as those abovereferred to so that the operator of the lasting machine will be relievedof the necessity of performing them manually before starting the lastingmachine and which can be relied upon to operate rapidly and effectivelyand to insure accuracy and substantial uniformity of adjustment of theuppers on the lasts.

With this and other objects in view, one feature of the inventionconsists in the provision, in an assembling machine, of means fordrawing an upper tightly about the heel end of a last by a pull appliedat the forepart, and means for drawing the upper tightly across theforepart of the last and for securing its margin adhesively to an insoleon the last at the sides of the forepart only while leaving the upperaround the end of the toe unsecured. In the machine herein illustrated alast having an insole and an upper loosely mounted thereon is supportedbottom downward by means of a work support which comprises a toe restand a heel rest arranged to engage the toe and heel portions,respectively, of the insole. As shown, a toe gage and two side gages areassociated with the toe rest for positioning the insole with the edge ofits forepart alined with the corresponding edge of the last bottom andfor positioning the last with the upper and the insole in position to beoperated upon, the gages being arranged to extend between the upper andthe last and to engage the edge of the insole and the edge of the lastbottom, and the toe gage serving also to hold the last against forwarddisplacement during the action of the operating parts of the machine.These operating parts, as herein shown, comprise a foredraw member, .twoside wipers,'and two overlaying devices all of which are normallyretracted from work-engaging positions to facilitate introduction andremoval of the work. In the illustrated machine treadle-operatedmechanism is provided for moving the foredraw member into engagementwith the upper at a point above the toe of the last and for yieldinglypressing it toward the last to cooperate with the toe rest in clampingthe last, and power means rendered operative by movement of theabovementioned treadle thereafter moves the foredraw member in adirection to draw the upper forwardly and thereby to tighten it aboutthe heel of the last while at the same time continuing to exert clampingpressure upon the last. As illustrated, the side wipers are brought intoyielding frictional engagement with the upper at the opposite sides ofthe toe of the last and moved downwardly to tighten the upper widthwiseof the last, these wipers being brought to rest near the bottom edge ofthe last where they function to hold the upper in its tightenedcondition while the cemented margins of the upper are pressed againstand caused to adhere to the bottom face of the insole by the action ofthe overlaying devices. As shown, the overlaying devices comprise rollswhich are moved inwardly to lay the cemented margins of the upper overthe insole and are arranged to exert yielding pressure to secure themargins adhesively to the insole so that the upper will be held in itsadjusted and tightened condition while the work is being transferred tothe lasting machine.

The invention further consists in features of construction andcombinations and arrangements of parts hereinafter described and claimedthe advantages of which will be apparent tothose skilled in the art.

In the drawings, the invention is illustrated as embodied in anassembling machine which is particularly designed for attachment to alasting machine of a type especially adapted for use in the lasting oftennis shoes or the like in which the uppers are fastened to the insolesby cement, such a lasting machine being shown at H] in Fig. 1 and beingof the same general character as that disclosed and claimed in LettersPatent No. 1,843,232, hereinbefore referred to. Reference may be had tosaid Letters Patent if desired for a description of the construction andmode of operation of the lasting machine, although for the purpose of anunderstanding of the present invention it will be necessary only to knowthat a conveyor belt I2 is provided for carrying shoes away from thevicinity of the lasting machine after they have been operated upon andthat the conveyor belt is operated through worm gearing 14 from a shaftl 6 which is driven through sprocket wheels and a chain l8 by a shaft 26having on one end a'beveled pinion 22 operated by a bevel gear 24secured to one side of a gear wheel 26 which is continuously runningwhile the lasting machine is in operation.

The illustrated assembling machine comprises a casing 30 on the outsideof which theoperating instrumentalities of the machine are mounted, thecasing 30 being rigidly secured by means of screws 32 and a tie bolt 34to the rear of the lasting machine Ill. Located above the casing '30 andsupported thereby is a heel rest 36 and a toe rest '38 (Fig. 2) for theheel and toe portions, respectively, of a last, such as the last A,having an upper B and an insole C arranged in loose relation thereon. InFig. 2, for convenience of illustration, the casing 38 is shown in sucha position that the supporting surfaces of the heel rest 36 and the toerest 38 are horizontal butactually the casing 30 is so positionedrelatively to the lasting machine It), as shown clearly in Fig. 1, thatthe heel and toe rests are inclined lengthwise of the shoe so that thetoe end of the shoe points upwardly and thus the operator of theassembling machine, without having to bend forwardly or assume anunnatural position, may look downwardly upon the loosely assembled upperso as conveniently to observethe conditionof -'the upper as it is beingoperated upon by the instrumentalities of the machine. Associated withthe toe rest 38 are side gages 40 and a toe gage and abutment 42 whichrelatively locate the foreparts of the insole and the last and whichlocate and hold the last, with the loosely assembled upper and insolethereon, in position to be operated upon. The operatinginstrumentalities of the assembling machine are arranged higher than thecasing 30 at the rear thereof and comprise a foredraw member 46 forfrictionally engaging the top of the forepart of the upper and drawingthe latter forwardly to tighten it about the heel portion of the :last,two side wipers 48 for wiping the forepart of the upper downwardly overthe opposite sides of thelast, and two overlaying devices 50 forpressing thelower cemented margins of the upper upon the insole for thepurpose of securing them thereto.

The foredraw member 46 is adapted to be moved into frictional engagementwith the upper on the 'last by depression of a foot treadle 52 (Fig. 1).Continued downward movement of the treadle '52 initiates the operationof the foredraw member 46, the side wipers-48 and-the overlaying devices56 under power, the power being vtransmitted by sprocket wheels and achain 54 from the driven shaft 16 to a cam shaft 56 which-is journaledin bearings in the side-of the casing 36 and which carries a pluralityof cams "and also'a clutch 58 of suitable well-known form, the latterbeing connected with the treadle 52 by means of a treadle rod 60 andbeing operable to cause the cam shaft 56 to make a singlerevolution andthenautomatically come to rest.

The heel rest 36 comprises a flat plate arranged to engage the insolebeneath the heel end of the last. As best shown in Fig. 2, the heel restplate 36 is provided with a cylindrical stem 62 which extends throughand is arranged for lengthwise sliding adjustment in vertical bearings64 one of which is formed in a plate 66 which constitutes a cover forthe casing SO-and the-other of which is formed in a bracket 68 which isrigidly secured to the upper side of the cover .plate 66. The heel reststem 62 is externally threaded to receive aknurled nut 10 which islocated between a portion of the bracket-68 and the cover-plate 66 andis adapted to be turned to raise or lower the heel rest to accommodatelasts the bottoms of which have diflc'erent degrees of slope in theirshank portions. To prevent the stem 62 from turning in its bearings andthereby enabling it to be adjusted vertically by the turning of the nut10, akey 12 in the bracket 68 is received within a vertically elongatedkeyway M in .thestem 62.

The illustrated toe rest 38 comprises a fiat plate which is adjustablymounted upon a stationary bracket which projects from the side of thecasing 30, the toe rest plate 38 being arranged to support the last byengagement with the bottom face of the insole at the extreme forward ortoe portion of the latter. The toe rest 38 is ofsmall area, as shown inFig. 4,and is arranged with :its lateral edges spaced inwardlysubstantial distances from the edges of the insole and the last bottomso as not to interfere with the movements of the overlayingdevioes 50 inpressing the margins of the upper against the insole. .As shown, the toerest 38 has formed at its forward extremity an integral upstanding lug42 arranged'to engage the toe end of the insole and to project upwardlybeyond the insole so:as to engage also the toe end' of the last. The lug42 thus constitutes a fixed abutment for holding the last against theforward thrust of the foredraw member 46 so as aosazaspositively toprevent any forward lengthwise displacement of the last resulting fromthe action of the foredraw member. The lug 42 functions also as a gageto locate the last, with the upper thereon, in the desired lengthwiserelation to the operating instrumentalities of the machine and to alinethe edge of the insole with the edge of the last bottom at the tip ofthe toe. In order that the toe gage and abutment 42 may be adjusted toaccommodate lasts of different sizes and styles, a rib 82 (Figs. 3 and5) formed on the lower side of the toe rest plate 38 is dovetailed forsliding adjustment in directions toward and from the heel rest 36 in aslideway 8 3 formed in the upper portion of the bracket 80 and a handscrew 86 is provided for effecting such adjustment. As shown, the handscrew 35 extends into a bore in the rib 82 on the toe rest 38, thethreads on the screw engaging screw threads formed within the bore whileat its opposite end, the screw 86 extends through and is arranged toturn freely within a. bearing lug 88 on the bracket 80. The screw 86 isheld against longitudinal movement in its bearing in the lug 88 by meansof a collar 89 on the screw, arranged to engage one end of the bearinglug 88, and a knurled head 90 which is arranged to engagethe oppositeend of the bearing lug and by means of which the screw 86 mayconveniently be turned for the purpose of adjusting the toe rest 38 andthe toe gage and abutment 42.

The side gages 40 function to aline the lateral edges of the insole withthe corresponding edges of the last bottom at the forepart of the lastand, in addition, to locate the last, with the upper and insole looselyassembled thereon, in a central position relatively to the side wipers48 and the overlaying devices 50. As a result of this arrangement theside wipers will so act upon the opposite sides of the upper inconforming the upper to the curve of the last as to insure against anytendency of the upper to slip sidewise in such a manner as to displacethe throat opening in the upper from the desired central position on thelast or to cause the tip line D of the upper to be improperlypositioned. This arrangement further insures that the overlaying devicesshall operate with the best results in securing the margins of the upperto the insole.

As shown in Fig. 3, the side gages 40 comprise vertically disposedfingers the lower ends of which are pivoted at 92 to ears 93 on a slide94 which is movable in a vertical slideway comprising guiding facesformed at the inner sides of parallel fianges 95 on the casing 38 sothat the side gages, after having performed their locating functions,may be lowered out of the way of the side wipers G8 and the overlayingdevices 50 to avoid interference with the latter as will be hereinafterexplained. The illustrated gage fingers 40 are formed at their upperends with substantially horizontal faces 96 for engagement with theopposite marginal portions of the lower surface of the insole tocooperate with the toe rest 38 in supporting the insole and the last,and with upstanding lugs 98 (best shown in Fig. 3) for engagement withthe opposite edges of the insole substantially in the plane of the tipline of the upper, if the upper has a toe tip, and for overlapping theadjacent edge portions of the sides of the last. These side gage lugs 98function relatively to position transversely the forepart of the insoleand the forepart of the last. The side gage fingers 40 are adjustabletoward and from each other to'accommoda-te insoles and lasts ofdifferent widths and means is provided for adjusting the gage fingers,this meanscomprising two manually operable bell-crank levers I (see Fig.4) which are pivoted at I02 to a portion of the casing 30 and arearranged with the free ends of their longer arms extending between andoperatively engaging the gage fingers. As shown, the gage fingers 40 areheld yieldingly against the arms of the bell-crank levers I00 by meansof springs I04 (Fig. 3) acting upon extensions I06 of the gage fingers.The shorter arms I08 of the bellcrank levers I00 extend toward eachother and are formed at their ends with gear segments IIO the teeth ofwhich intermesh, the arrangement being such as to maintain the leversI00 with the ends of their long arms equidistant from a vertical planewhich is centrally disposed relatively to the side wipers 48 and theoverlaying devices 50, and consequently to maintain the side gagefingers in a similar relation to that plane so as to insure uniformityof action of the side wipers 48 and overlaying devices 50 upon oppositesides of the upper. For the purpose of operating the bellcrank leversI00 to adjust the side gage fingers 40 toward or from each other anadjusting screw I I2 is provided, the screw I I 2 extending through andhaving threaded engagement with blocks I I4 (see Fig. which are swiveledupon the long arms of the levers I00, the pitch of the threadscooperating with one of the blocks II4 being opposite to the pitch ofthe threads cooperating with the other block so that turning of thescrew IIZ'in one direction will result in moving the levers I00, andconsequently the gage fingers 40, simultaneously in opposite directions.The screw II2 extends outwardly through an opening in the casing 30 andis provided, outside of the casing, with a knurled head Hi3 by means ofwhich the screw may be turned to effect a desired adjustment of the gagefingers 40.

It will be seen from the foregoing that a last having an upper and aninsole loosely assembled therewith is supported, while the upper isbeing operated upon in this machine, by means of the heel rest 36 andthe toe rest 38 and that the hori- I zontal faces 96 on the side gagefingers 40 assist in supporting the forepart of the last until they arelowered to make way for the side wipers 48 and the overlaying devices50. It will also be seen that the forepart of the insole is located withits edge registering with the edge of the last bottom by means of theside gages 40 and the toe gage 42, that the last with the upper and theinsole thereon is located lengthwise with respect to the operatinginstrumentalities by means of the toe gage 42, and that the last islocated widthwise in position for the upper to be operated upon by meansof the side gages 40. Moreover, the side gages 50, whatever theirpositions of adjustment, are located equidistant from a vertical planecentrally disposed with respect to the foredraw member 46 so as toinsure that the foredraw member will act upon the central portion of theupper as well as to insure substantial uniformity of action of the sidewipers and the overlaying devices upon opposite sides of the upper.

The foredraw member at (as best shown in Figs. 2 and 5) consists of alever which is fulcrumed upon a horizontal pin I20 that is locatedsomewhat below and forwardly of the toe of a last supported by the heelrest 36 and the toe rest 38. The foredraw lever 45 is curved upwardlyand forwardly from its fulcrum pin I20 to overlie the toe of the lastand its upper free extremity is provided with a pad I22 of soft rubberor other yieldable material adapted 'to conform readily to the curvatureof the last-when pressed against the latter so as to secure firmfrictional engagement with the upper without having any tendency toinjure the latter. When the machine is idle the foredraw lever 46 iselevated somewhat above the position in which it appears in Fig. 2 tofacilitate the placing of the last in position upon the toe rest 38. Thelever 46 is swung downwardly by means of the foot treadle 52 to bringthe pad I22 into the position shown in Fig. 2 for engagement with theupper, and thereafter the fulcrum pin I20 is moved by power in adirection lengthwise of the last to move the lever 46 bodily forward forthe purpose of foredrawing the upper and tightening it about the heel ofthe last. To permit the fulcrum pin I20 to be moved as just described itis: supported by a yoke I24 which embraces the lever and is carried atthe forward end of a plunger I26 which extends through and is adapted toslide within a horizontal bore in the bracket 80, the plunger beingacted upon by a spring I 28 tending to move it in a direction to hold ashoulder I30 on the yoke I24 seated against the outer end of the bracket80. As shown, the spring I28 is connected at one end to the plunger I26and at its opposite end to an adjusting screw I32 which extends throughan aperture in the casing 38 and is provided outside of the casing witha wing nut I34 which may be turned to vary the tension of the spring.For the purpose of swinging the foredraw lever I46 about its fulcrum pinI20 into and out of engagement with the work and moving the lever 48bodily to draw the upper forwardly on the last the lower arm I36 of thelever 46 is connected by a rod I38 with the upwardly extending arm I40of a three-arm lever which is pivotally mounted upon a fixed horizontalrod I42, the three-arm lever having a downwardly extending arm I 44which carries a cam roll I 46 arranged to engage the periphery of a camI48 on the cam shaft 56 and a second downwardly extending arm I50 whichis connected by means of a rod I52 with the foot treadle 52. A springI54 secured at its upper end to the casing 30 and at its lower end tothe rod I52 tends to turn the three-arm lever I40, I44, I50 in adirection to hold the cam roll I46 in engagement with the cam I48, andto hold the foredraw lever in its normal elevated position. Upondepression of the treadle 52 the roll I46 is carried away from the camI48 and the foredraw lever is swung downwardly to press the pad I22 intofirm frictional engagement with the upper, after which continueddownward movement of the treadle 52 will operate, through the treadlerod 60, to throw the clutch 58 and thus to start the operation of themachine under power. During the operation of the machine under power theroll I46 is engaged by the cam I48 and the foredraw member 46 isoperated to tighten the upper upon the last.

As shown, the treadle rod 60 is connected at its upper end with aclutch-controlling lever I58 which is pivoted at I60, the upper portionof the rod 60 having a pin-and-slot connection I62 with the lever I58arranged to permit the rod60 to move downwardly without moving theclutch-controlling lever I58 until after the foredraw pad I22 hasengaged the upper. The clutch 58 is a clutch of the Horton type which isso well known that it need not be particularly described. It will beunderstood, however, that this clutch has friction rollers adaptedrotatably to connect its two elements of which the outer element I64(Fig. 1)

ispinned to the cam shaft 56 while the innerelement IE6 "is fixed to a"sprocket wheel I68 that :is carried by the cam shaft 56 and over whichpasses the sprocket chain 54. The friction rollers of the clutch 58 arenormally heldout of operation by means comprising a controller ring I10(Fig. 2) provided with a shoulder I12 arranged to cooperate with thehooked extremity of the clutch controlling lever I58. Theclutch-controlling lever I58 is held in operative position by means of aspring (not shown). When the lever I58 is momentarily disengaged fromthe controller ring I10 by depression of the foot treadle 52 the clutch58 operates to imp-art asingle rotation to the cam shaft 56 and the camsthereon and is then arrested by engagement of the lever I58 with theshoulder I12. As soon as the clutch is thrown into operation the cam I48moves the three-arm lever I40, I44, I50 in a counterclockwise directionand, through the rod I38, moves the foredraw lever 46 bodily toward theleft, the plunger I 26 sliding outwardly against the tension of thespring I28 to permit such movement of the lever 46 to take place. Duringthis bodily movement of the lever the latter is constantly urged aboutits fulcrum I20 in a direction such that the foredraw pad I22 iscontinually held in firm frictional engagement with the upper.

The side wipers 48 comprise pads of soft rubber or the like which aresecured to the inwardly turned upper ends of two levers I18 arranged oneat either side of the forepart of the last so that the pads will engagethe upper approximately in the plane of the tip line, the levers I18having inwardly turned lower extremities which are pivoted at I to earsI 82 which project in opposite directions from a slide I84 that ismounted below the slide 94 for up-and-down movement in the guidewayformed by the vertical guiding faces 95 already referred to.Substantially midway between the upper and lower ends of the levers I18these levers are connected together by means of a spring I86 which tendsto swing the levers toward each other, the inward movements of thelevers under the influence of the spring being limited by engagement ofrolls I88 carried by the levers with inclined cam faces I90 formed onplates I92 which are rigidly secured by means of screws I94 to theoutside of the casing 30. The slide I84 is connected by means of a linkI86 with the upper end of a cam lever I98 (Fig. 2) which is pivotallymounted upon the rod I42 and which carries at its lower end a cam roll200 arranged to engage the periphery of a cam 202 on the cam shaft 56. Aspring 204, connected with the lever I98, tends to swing the lever in adirection to hold the slide I84 in its upper position and to hold theroll 200 against its cam. When the machine is idle the levers I18 occupythe positions shown in Fig. 3 with the side wipers 48 spaced upwardlyand outwardly with respect to the upper on the last. Upon rotation ofthe cam shaft 56 the cam 202 operates to rock the lever I98 in adirection to lower the slide I84 and to move the side wiper levers I18downwardly. As the levers I18 move downwardly the spring I86 operates toswing the levers inwardly about their pivots I80 under the control ofthe cam faces I98 until the side wipers 48 engage the upper and are heldin firm frictional engagement therewith by means of the spring I86. Thecam faces I90 are designed to cause the side wipers 48 to engage theupper at points spaced outwardly from the foredraw member 46 and as thelevers I18 continue to move downwardly the spring I86 yields to permitthe side wipers to separate as required to follow the curved contour ofthe last while serving to maintain frictional engagement of the sidewipers with the upper so as to wipe the upper downwardly over theopposite sides of the toe portion of the last and thus to tension ittransversely in the vicinity of the tip line.

As shown, the overlaying devices 50 are in the form of rolls, the rollsbeing carried in the forked upper extremities of two plungers 200 whichare guided for sliding movements in sockets 208 (Fig. 3) formed in theupper arms of two levers 2 I 0 which are mounted for swinging movementstoward and away from each other about fixed pivots 2 I2. The lowerportion of each plunger 206 is bored as indicated at 2 I4 to receive aspring 2| 6, the upper extremity of which bears against the uper end ofthe bore 2M and the lower end of which is seated against the bottom ofthe socket 268. Upward movement of each plunger 205 in its socket 208 islimited by means of a stop screw 2I8 carried by the plunger and arrangedto engage the lever 2 I 0 at the upper end of a slot 220 in the lever.The levers 2I0 extend downwardly below their pivots 2I2 and areconnected together at their lower ends by means of two toggle links 222and 224, the outer ends of which are pivoted at 226 to the levers 2H]and the inner ends of which are pivotally connected with each other bymeans of a screw 228 which serves also to secure the toggle linkspivotally to the slide 94 which also carries the side gage fingers 48.The slide 94 is connected by means of a link 230 (Fig. 2) with one armof a lever 232 that is mounted to turn on the rod I42, and the other arm234 of which carries a cam roll 236 arranged to bear upon the peripheryof a cam 238 on the cam shaft 55. A spring 240 (Fig. 4) connected withthe lever arm 232 tends to hold the slide 94 in its uppermost positionand to hold the roll 236 against its cam. The cam 238 opcrates to lowerthe slide 94 and to straighten the toggle 222, 224, the straightening ofthe toggle moving the overlaying devices inwardly to press the marginsof the upper against the insole and the lowering of the slide 94withdrawing the side gages 40 from the paths of the side wipers 48 andthe overlaying devices 50.

To prepare the upper of a tennis shoe orsneaker to be operated upon bythe lasting machine ID the operator of the above described as semblingmachine, after having first placed an upper and an insole in looselyassembled relation upon a last, presents the last and the parts there onright side up to the assembling machine, po-

sitioning the last so that the toe and heel portions of the insole restupon the toe rest 38 and the heel rest 36, respectively, with the toe ofthe last beneath the foredraw member I22 (which is elevated somewhatabove its work-engaging position) and thrusting the last forwardly toengage the edge of the insole and the edge of thelast bottom with thetoe gage 42 and with the side gages :10. It will be understood that theheelrest 36 has been previously adjusted vertically by manipulation ofthe nut I0 into positionto cooperate properly with the toe rest 38 insupporting the last and that the gages 40 and 42 have been adjusted bymeans of the screws I I2 and 86, respectively, as may have been requiredin accordance with the size and style of the particular last beingoperated upon. It should also be understood that the lower margin of theupper has previously been coated on its inner side with cement whichwill cause the upper to become firmly secured to the insole when pressedagainst the insole by the overlaying rolls 50. The gages 40 and 42project upwardly between the upper and the sides of the last, the toegage 42 functioning to aline the edges of the insole with the edge ofthe last bottom at the tip of the toe and to locate the last and theparts thereon lengthwise in position to be operated upon, while the sidegages 40 aline the opposite lateral edges of the insole and the lastbottom at the forepart of the last and serve to locate the forwardportions of the last, the upper, and the insole widthwise in properrelation to the operating instrumentalities of the assembling machine.

The work having been presented to the assembling machine and positionedthereon as above described, the operator depresses the foot treadle 52,thereby causing the foredraw lever 46 to be rocked by foot power aboutits pivot I20 to lower the pad I22 into frictional engagement with theupper, in which position the member I22 cooperates with the toe rest 38in clamping the work so as to prevent the last and the insole from beingdisplaced while the upper is being operated upon. The shoulders 96 onthe side gage fingers 40 also cooperate with the pad I22 in the initialclamping oi the work. As the treadle 52 is moved further downward by theoperator the clutch 58 is tripped and the machine starts to operateunder power. At the beginning of its cycle of operations under power themecha, nism operated by the cam I48 functions to move the pivot I20 oithe foredraw lever 40 forwardly relatively to the last, while at thesame time exerting a force tending to rock the lever 46 about its pivotI20 so as to maintain the pad 122 in efiective holding engagement withthe upper. As the downward pressure on the pad I22 is maintained and asthe pad I22 moves forwardly of the last under power as a result of theforward movement of the pivot I20, the upper is drawn forwardly towardthe toe of the last and is thus tightened about the heel end and alongthe sides of the last. During the above foredraw movement of the memberI22 the mechanism operated by the cam 202 lowers the side wipers 48, thespring I moving the side wipers inwardly, under the control of the camfaces I90, into yielding frictional engagement with the upper atopposite sides of the foredraw lever 56, and causing the wipersyieldingly to wipe the upper downwardly over the forepart of the last totension it widthwise of the last, and finally holding the side wiperspressed against the upper in the positions in which they appear in Fig.6 to maintain the upper in tensioned condition during the laying of itslower marginal portions over the insole. During the downward movementsof the side wipers G8 the mechanism actuated by thecam 238 starts tostraighten the toggle 222, 224, thereby moving the overlaying rolls 50toward each other and at the same time lowering the slide 94 and theside gages 40. The side gages 40 are lowered to positions suflicientlybelow the insole to avoid interference with the operative movements ofthe side wipers and the overlaying rolls. The overlaying rolls engagethe downwardly projecting margins of the upper and, after the sidewipers have completed their downward Wiping movements, the overlayingrolls move inwardly to the positions shown in Fig. '7, during whichmovements they lay the upper. margins against the lower face of theinsole and press them firmly against the insole so that the portions ofthe upper margins engagedby the rolls will be secured to the insole bymeans of the cement on the inner sides of the margins of the upper. Thusthe upper is securely heldin its tensioned condition. upon the last sothat it will not become displaced during the transfer of the last to thelasting machine. During the latter part of the cycle of operations ofthe assembling machine the operative parts of the machine ar returned totheir starting positions to facilitate the removal of the work which hasbeen acted upon and permit the presentation of a new piece of work tothe. machine. The foot treadle having been released by the operatorshortly after the starting of the cycle of. operations, the clutch leverI58 is returned into position to function, after the cam shaft 5? hascompleted a single revolution, to stop the machine with the operativeparts in the positions shown in Fig. 1 ready for the performance of.another assembling operation.
